Title: Process for treating crude petroleum oils
Inventor: ALLIBONE BERNARD CHARLES
IPC: C10G31/06
Filed: 1960-11-01
Abstract: A wax-containing crude petroleum oil is first heated to at least that temperature at which all the wax is in solution in the oil, and preferably 20 DEG -30 DEG F. above that temperature, and is then cooled to below 75 DEG F., preferably not lower than 40 DEG F., to repreciptiate the wax, the cooling over at least the major part of the temperature range within which the wax is precipitating being at a rate within the range of 0,1 DEG -5 DEG F. per minute, and under conditions such that no substantial mixing movement is induced in the oil.  The controlled cooling may be in a vertical tube heat exchanger, for example with the oil being in the shell and the cooling medium being supplied simultaneously to the lower end of each tube.  Preferably the ratio of heat transfer surface to oil capacity should be not less than 10 sq. ft. per cu. ft.  The wax is precipitated in the form of large discrete crystals which remain suspended in the oil and are non-sensitive to shearing, and thus have a reduced tendency to thicken the oil, which may thus be pumped more readily.

[Class 39 (ii)] [Also in Groups II, XXX and XXXVI] A machine for making glass stem elements for lamps, valves or the like comprises means for receiving and conveying a glass flare 41, Fig. 8, to a succession of stations at which the glass exhausting tube 45 and lead-in wires 44 are positioned relatively to the flare, a pinch or press is formed to combine the flare, tube and wires, air is blown in the tube to produce a hole at the pinch through which the lamp is exhausted, the end of the tube 45 is flattened at 239, Fig. 7, to accommodate the filament support wires, and the finished stem is discharged. The flares and tubes are held in heads 22 on a horizontal chain conveyer 10, and the tubes and wires are positioned relatively to the flares by means on a lower chain conveyer 9 which means are in alignment with the heads 22 over the operative part of the conveyer paths. The conveyers and means for supplying the flares and exhausting tubes thereto, for holding them in correct relative positions, and for discharging the finished stem are described in Group XXX, and the means for selecting lead-in wires singly from a supply hopper are described in Group II, and the means for delivering the wires in correct relationship with the flare and tube are described in Group XXXVI. The flares, tubes and lead-in wires having been arranged in correct relationship and being held in holders on the conveyers, then move past burners to fuse the flare and tube, a pair of dies 232, or a succession of pairs of dies, being provided to form the press of the tube. Blasts of air are now admitted to the tubes 45 to open an exhausting hole in the softened glass. The dies 232, Fig. 36, flatten the flare by movement towards one another in a line transverse to the path of the heads 22, the dies being pivoted at 236 and operated in synchronism by links 238 connected to a member 240 which is urged upwards by a spring 243, is moved downwardly by a rod 242 actuated by a cam 247 and is splined on a revolving shaft 234 which carries the whole of the mounting for the dies. The shaft 234 is oscillated by a cam 251 and linkage 249, 248 so that the dies are swung bodily through a right-angle and are thus removed from the path of the work piece before it moves forward to the next station. The stems now pass burners which heat the tip 252, Fig. 7, of the tube 45 to permit the formation of a button 239 by a reciprocating plunger preparatory to the unloading operation.

Title: Process for the treatment of articles consisting of synthetic polymers and products obtained thereby
IPC: D06M13/224
Filed: 1962-10-11
Abstract: An article e.g. a fibre, yarn or film of a linear polyester is treated with a complex formed from boron trifluoride and an organic compound having a doublet of free electrons (lone pair) readily accessible to the boron trifluoride.  Such compounds may include alcohols e.g. methanol alkylene glycols e.g. ethylene glycol, ethers e.g. diethyl ether, esters of alkanoic acids e.g. ethyl acetate and ethyl formate, and heterocyclic compounds, especially cyclic polymethylene mono- and diethers e.g. tetrahydrofuran and dioxan. The polyesters may be obtained from aromatic diacids such as terephthalic acid, isophthalic acid 3, 5-dicarboxy-phenol and 4, 41-dicarboxy-diphenyl-sulphone and diols e.g. ethylene glycol and di-(hydroxymethyl) 1, 4-cyclohexane.  The complex may be used in the pure state, or as a solution in the organic constituent or other solvent.  The duration of the treatment, depending on the complex and temperature used, e.g. 25 DEG  to 100 DEG C., may be from a few seconds to 2 hours.  The article may be immersed in a heated bath p containing the complex or a solution thereof, or the article may be impregnated with the complex at ambient temperature e.g. by atomisation, padding or immersion, and then heated by passing it through an oven.  The treated articles are preferably washed to remove excess complex, with e.g. the organic complexing constituent or water, to which an alkali e.g. sodium bicarbonate or a surface-active agent has been added.  When washing with water, the solution recovered by centrifuging must have a pH of at least 6.  The treated articles have an increased affinity for dyes, especially basic and disperse dyes.  Fabrics obtained according to the invention have a reduced tendency to pilling.  In a typical example, a yarn of polyethylene terephthalate is treated with the complex of boron trifluoride and ethyl acetate for 1 minute at 100 DEG C.  After washing with sodium bicarbonate, then with water, and drying at 50 DEG C., the yarn is dyed at 100 DEG C. with "Bleu Astrazon 3RL".

In making a chain link the end surfaces of two U-shaped chain link parts are welded together under a pressure of 4-6 kg. per square mm. and a current of 50-80 amps. per square mm., and each end surface is formed so that prior to welding, contact between the end-surfaces is only substantially at the centre of each endsurface and the gap between the end-surfaces increases in the radial direction. A die 18 secured to the bed 39 of a machine co-operates with a die 19 movable vertically by a piston device 21 and similar dies 13, 14 are mounted on a frame 20 rotatable about pivots 22 and movable towards or away from the dies 18, 19 by a piston device 24 acting through members 23. A cylinder 31 movable axially by a piston device 26 and rotatable by a piston-operated rack-andpinion drive is slidable in a sleeve 38 on the bed. A pair of support-arms 11, 16 are carried by the cylinder 31 and can pass through the dies when vertically-arranged. In operation a half-link 17 engaged with the end of the chain is clamped in dies 18, 19 and a half-link 9 is clamped in dies 13, 14 and engaged with a half-link 8 held by the arms 11, 16. The half-links 17, 9 are brought into contact by the piston device 24 and current switched on and welding pressure exerted. After welding, the dies 13, 19 are raised and the cylinder 31 moved rearwardly, Fig. 3, to withdraw the link half 8 clear of the dies, the cylinder is then rotated through 90 degrees and moved to insert the link part 8 between dies 18, 19. The arms 11, 16 release the part 8, are withdrawn, turned through 90 degrees and fed forward through the dies. A pair of engaged link halves 4, 5 held in a slotted member 6 with the half 4 engaged by a magnet 3 are meanwhile fed into the dies 13, 14 by a piston device 1. The part 5 is clamped by the dies 13, 14, the part 4 is held by the arms 11, 16 and the magnet 3 is returned. The welding is then effected as before. If means are provided for removing welding burr the arms 11, 16 do not hold a link half during welding and means are provided on the dies 13, 14 for this purpose.
